Oct 20, 2026, 6:28 PMCapital investment in decades of painstaking research richly pays off by making a model possible:
''We find that slow bedrock adjustment weakens the stabilizing effect of glacial isostatic adjustment, allowing grounding lines to reach retrograde bed slopes more readily and triggering self-sustained retreat below the bifurcation threshold. Although the West Antarctic Ice Sheet is subject to a bifurcation, it is unlikely to experience rate-induced tipping because of the low mantle viscosity beneath the region. In contrast, the Recovery and Aurora subglacial basins are likely to undergo such a transition even under warming rates lower than those observed today.''
